Subject: [PATCH] ARM: dts: rockchip: Make rk3288-veyron-mickey's emmc work again
Date: Fri, 3 May 2019 16:45:37 -0700 [thread overview]
Message-ID: <20190503234537.230177-1-dianders@chromium.org> (raw)
When I try to boot rk3288-veyron-mickey I totally fail to make the
eMMC work. Specifically my logs (on Chrome OS 4.19):
mmc_host mmc1: card is non-removable.
mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)
mmc_host mmc1: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0)
mmc1: switch to bus width 8 failed
mmc1: switch to bus width 4 failed
mmc1: new high speed MMC card at address 0001
mmcblk1: mmc1:0001 HAG2e 14.7 GiB
mmcblk1boot0: mmc1:0001 HAG2e partition 1 4.00 MiB
mmcblk1boot1: mmc1:0001 HAG2e partition 2 4.00 MiB
mmcblk1rpmb: mmc1:0001 HAG2e partition 3 4.00 MiB, chardev (243:0)
mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)
mmc_host mmc1: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0)
mmc1: switch to bus width 8 failed
mmc1: switch to bus width 4 failed
mmc1: tried to HW reset card, got error -110
mmcblk1: error -110 requesting status
mmcblk1: recovery failed!
print_req_error: I/O error, dev mmcblk1, sector 0
...
When I remove the '/delete-property/mmc-hs200-1_8v' then everything is
hunky dory.
That line comes from the original submission of the mickey dts
upstream, so presumably at the time the HS200 was failing and just
enumerating things as a high speed device was fine. ...or maybe it's
just that some mickey devices work when enumerating at "high speed",
just not mine?
In any case, hs200 seems good now. Let's turn it on.
